In-depth Analysis of the Full Process of Xiamen Import Customs Clearance Agency: 2026 Latest Operation Guide

Xiamen Port Import Customs Clearance: A Key Node in Supply Chain Efficiency

It is estimated that the container throughput of Xiamen Port will exceed 14 million TEUs in 2026,and the proportion of import full containers will continue to rise.For enterprises engaged in the import of food,mechanical equipment,chemical products and other categories,the customs clearance timeliness after the cargo arrives at the port directly determines the storage cost,production line schedule and even customer delivery commitments.Mr.Liu’s company mainly imports Southeast Asian fruits,and once had cargo stranded at the terminal for 5 days due to defects in customs clearance documents,and the resulting detention charges and losses almost offset the profit of the entire order.This case shows that import customs clearance is not a simple "submit documents,wait for release",but a complex project involving multiple professional links such as access review,commodity classification,price verification,and compliant declaration.Zhongshen has been deeply engaged in Xiamen Port for 20 years,having handled more than 30,000 import customs clearance cases,and this article breaks down this experience into four operable core stages.

Stage 1: Pre-access and Document Preparation

The goal is to confirm that the goods have the legal qualification to enter the Chinese mainland market and prepare all the certification documents required by the customs,inspection and quarantine and other departments.In 2026,the General Administration of Customs will accelerate the update frequency of the access list for sensitive commodities such as food,cosmetics and medical devices.Some enterprises did not check the latest policies before shipping the goods,resulting in being unable to declare after the goods arrive at the port.

The key actions include three items: First,query the supervision conditions corresponding to the commodity HS code through the "China International Trade Single Window" to confirm whether an import license,CCC certification or animal and plant quarantine approval is required; Second,check whether the documents provided by the shipper such as certificate of origin,health certificate and composition analysis report meet the format and content requirements of China Customs; Finally,for commodities involving brand authorization or patented technology,prepare the authorization letter or technical description letter from the right holder in advance.

Common problems focus on document discrepancies and classification disputes.Manager He once handled an import of Italian wine,and the health certificate issued by the foreign winery did not indicate "sulfur dioxide content",which was directly rejected by Xiamen Dongdu Customs.The core role of Zhongshen at this stage is pre-review.Our customs team will pre-review the full set of documents 48 hours before the goods are loaded,and communicate with the customs classification department in advance on elements that may cause disputes.In 2026,we launched the "Document Cloud Pre-review" service,which automatically compares with the latest customs templates through OCR recognition technology,increasing the document compliance rate to over 98%.

Stage 2: Arrival Declaration and Customs Inspection

After the goods arrive at Xiamen Port,the declaration and pickup must be completed within the 14-day free detention period,and additional fees will be incurred for each day of delay.The goal of this stage is to pass the customs system review as quickly as possible and efficiently respond to possible inspection instructions.

The key actions are broken down as follows: After the shipping company exchanges the bill of lading,immediately submit the import customs declaration form through the Single Window,accompanied by electronic data such as invoices,packing lists and bills of lading; In the system document review link,the customs risk analysis model will logically verify elements such as price,classification and origin,and about 30% of the declaration forms will enter the manual document review queue; For goods that trigger inspection instructions,arrange a trailer to transport the container to the designated inspection yard within 3 hours to cooperate with the customs for unpacking,sampling and machine inspection.

Inspection delay is the biggest pain point in this stage.Mr.Meng’s mechanical parts import business once had goods stranded at the inspection yard for two weeks due to the deviation in the understanding of the "used mechanical and electrical products" judgment standards by the customs.The on-site team of Zhongshen stationed in Xiamen Haicang Port handles more than 50 inspection businesses every day,and we have established a two-way communication mechanism with the Inspection Section and Logistics Section.After the General Administration of Customs promoted the "Smart Inspection" system in 2026,we can obtain the inspection priority ranking in advance,apply for "green channels" for fresh and cold chain goods with high timeliness requirements,and reduce the average inspection time from 3.5 days to 1.2 days.Our system can also track the container location in real time,avoiding additional container relocation fees caused by information lag.

Stage 3: Tax Calculation and Payment

Accurate calculation of tariffs,value-added tax and consumption tax is the financial core of successful customs clearance.In 2026,Xiamen Customs has tightened the review of royalty fees and the impact of special relationships on transaction prices,and the number of cases where the dutiable value declared by enterprises is questioned has increased by 40%.

The key actions include: Calculate tariffs according to the dutiable value approved by the customs,applying the most-favored-nation tariff rate or agreed tariff rate; For commodities involving anti-dumping and countervailing duties,collect additional deposits; Pay taxes online through the "Self-declaration and Self-payment" function of the Single Window and obtain electronic tax receipts.It should be noted that some commodities apply provisional tariff rates or preferential tariff rates of free trade agreements,and the original certification documents need to be declared actively and submitted.

Price questioning and incorrect tariff application are frequent problems.Manager Qian’s chemical import business once had a price check initiated by the customs valuation department due to "different prices for the same family of products",with the tax repayment amount as high as 15% of the cargo value.The finance and taxation team of Zhongshen provides two core values in this link: First,use the WTO Valuation Agreement rules to prepare complete price reasonableness explanation materials for customers,including industry price indexes,third-party assessment reports,etc.; Second,accurately grasp preferential policies such as RCEP and China-ASEAN Free Trade Agreement.In 2026,we helped customers save an average of 8-12% of the tariff costs compared to the payable taxes.Our system has built-in price databases of Xiamen Port in the past three years,which can quickly match the customs valuation range and early warn price risks.

Stage 4: Release,Pickup and Follow-up Services

After obtaining the customs release order,the pickup must be completed within 24 hours,otherwise high terminal storage fees will be incurred.The goal of this stage is not only to transport the goods out of the port area,but also to ensure the closed-loop of subsequent supervision procedures and avoid compliance risks.

The key actions include: Go to the terminal to handle the container pickup procedures with the customs release slip,and arrange a trailer to transport the goods to the designated warehouse; For statutory inspection goods,make an appointment for the warehouse inspection by the commodity inspection department; For bonded or tax-reduced and tax-exempt equipment,handle the follow-up supervision manual according to regulations.In 2026,Xiamen Port has implemented "paperless pickup",and enterprises need to confirm the electronic pickup order in the system,which poses a new challenge for enterprises that are not familiar with online operations.

Subsequent supervision omissions are often overlooked pitfalls.After importing tax-reduced and tax-exempt equipment,Mr.Chai was fined and required to make up taxes because he failed to report the equipment usage status on time within the customs supervision period.The value-added services of Zhongshen cover the 30-day observation period after pickup.We establish "customs clearance files" for customers and automatically remind them of subsequent supervision nodes.Our logistics cooperation network covers 12 major storage points inside and outside Xiamen Island,and can match professional storage resources such as constant temperature warehouses and dangerous goods warehouses according to the characteristics of the goods.Data in 2026 shows that the average timeliness of import goods represented by us from release to storage is 4.8 hours,which is 60% faster than that handled by enterprises themselves.

Core Value of Zhongshen’s Services

Import customs clearance is not an isolated link,but an amplifier of supply chain efficiency.After 20 years of accumulation at Xiamen Port,Zhongshen has formed three irreplaceable competitive advantages: First,data assets: we have accumulated more than 80,000 historical customs clearance cases and can quickly identify risk patterns; Second,organized collaboration: the customs,logistics and finance and taxation teams work under the same SOP instead of acting alone; Third,technology embedding: our system has achieved API docking with Xiamen Single Window,major shipping companies and inspection yards,with zero delay in information flow.In 2026,the average customs clearance timeliness of our customers is 2.3 working days,and the inspection rate is controlled within 5%,both of which are 40% better than the average level of Xiamen Port.The essence of choosing a professional agency is to transform the uncertain customs clearance process into predictable and manageable supply chain nodes,which is exactly the value that Zhongshen continues to create.
